Ain't Been Done:
Jessie J sings: "Imma do it like it ain't been done," and I'm not sure if she's professing her unknown sexual talents or she thinks she's the shit. Probably both.

Masterpiece:
This track is a mid-tempo (power?) ballad. She coos: "I still on my face sometimes. Can't color inside the lines," confirming she's a three-year-old trapped in an insanely sexy 20-something year old's body. Really though, it's about the world not seeing the best of her... yet.
